Battery Module Housing Cutouts for Compact Thermal Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules face challenges in minimizing installation space, particularly height, when connecting to external temperature-control elements for efficient heat transfer.
Innovation Solution
The battery module features mechanical connecting elements as upper and lower cutouts on its end side, connected by a through-passage, allowing for a single mating piece to be fixedly connected to the temperature-control element, enabling good heat transfer without additional height requirements and accommodating different temperature-control element sizes and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If mechanical connecting elements are provided as corresponding upper and lower cutouts connected by a through-passage, then the installation space (height) is minimized, but the complexity of the housing structure increases
Solution Approach 1:
The housing end side is segmented into upper and lower cutouts that are connected by a through-passage, allowing the connecting means to pass through and enabling compact integration of the temperature-control element without increasing overall height
Solution Approach 2:
The connecting means is nested within the through-passage structure, with its head positioned in the upper cutout and its mating piece in the lower cutout, maximizing space utilization and minimizing the external dimensions of the assembly
2Ease of operation
If a single mating piece is used to connect to the temperature-control element, then the ease of connection is improved, but the adaptability to different temperature-control element sizes is reduced
Solution Approach 1:
The mechanical connecting elements are designed as universal features on the housing end side that can accommodate various temperature-control element sizes and positions. The upper and lower cutouts with through-passage provide a standardized interface that works with different mating piece configurations, enabling one housing design to serve multiple application scenarios

Function Achieved in This Case
This configuration allows for simple and stable connection of the battery module to various temperature-control elements, minimizing height requirements and ensuring effective thermal contact, suitable for use in compact battery systems with open-chamber designs.
Implementation Method 1
an end side of the housing has mechanical connecting elements for connecting the battery module to a temperature-control element which is provided outside the battery module in order to thereby enable good heat transfer between the battery module and the temperature-control element

AI summary
A battery module includes a plurality of individual electrical cells which are arranged within a common housing, wherein an end side of the housing has mechanical connecting elements for connecting the battery module to a temperature-control element which is provided outside the battery module in order to thereby enable good heat transfer between the battery module and the temperature-control element. The mechanical connecting elements are provided as corresponding upper and lower cutouts in the end side of the housing, which upper and lower cutouts are connected to one another by a through-passage, for receiving a connector of which the head can be positioned in the one cutout. The connector can extend vertically along the through-passage and can be connected to a mating piece which can be positioned at least partially in the other cutout and is fixedly connected to the temperature-control element.
